Other Settings
Item	Description
Max trend reads per collection	Indicates the maximum number of trend records to read for a collection.
Automatic alarm registration	Indicates whether the BACnet driver is configured as receiver of the alarm notifications in all the notification class objects. Default is enabled.
Force trend collection	Indicates whether the trend collection is forced by position for third-party devices. Default is disabled.
Use only read property	Indicates whether the ReadProperty service only is used for third-party devices that do not support the ReadPropertyMultiple service. Default is disabled.
Use get alarm summary	Indicates whether the GetAlarmSummary service is used for third-party devices that do not correctly support the GetEventInfo service. Default is disabled.
Trouble events (for fire system only)	Indicates whether Event List displays both incoming and outgoing Trouble events. This value is imported from the configuration file of the fire system's panels. Default is disabled.
Supervisory events (for fire system only)	Indicates whether Event List displays both incoming and outgoing Supervisory events. This value is imported from the configuration file of the fire system's panels.
Disallow subscriptions	Indicates that no COV traffic will occur for this device. The device will use polling only.
No MSTP link subscriptions	Indicates that no MSTP link subscriptions will occur for this device in order to reduce traffic on an MSTP network.
Hide BACnet Events	Indicates whether BACnet alarms, notify type Event, are hidden. If this box is checked, the alarms do not display in the event list, but they are recorded in the activity log.
No Resetting Device Alarms	Prevents a device alarm from being reset and erased while the device is still failed. The check box is unchecked by default.
No Link Subscriptions	Prevents the BACnet driver from making subscriptions for related items. The result is less network traffic in the driver and less polling of devices. NOTE: The BACnet driver reads the reference property once on startup and will not poll or subscribe to it. If you edit a BACnet object that references a related item, the edited object will not link to the correct related item until the BACnet driver restarts.
Check NC Rate	Indicates the interval in minutes the driver checks to see that the management station is still registered to receive alarms.
Delay After Write	Indicates the interval in milliseconds the driver waits after a command to read the value to see if it changes.
